I spent around 4 hours total working on this. It went through several design iterations, including one where it had the same urban camouflage pattern as the Iron Maiden. All in all, I'm very satisfied with it--The only parts I don't like is how the hatch on top doesn't open and that there's no engine block.

This one only took one hour to build. It originally started as an immortal gunship, but took on a vastly different form and color: The only things it retains are the "wings" and the vaguely insectoid cannon. I am completely satisfied with it.
